4.5 Earthquake Strikes Hawaii as Hurricane Iselle Looms

7 Aug 2014, 12:48 pm


As residents of Hawaii — especially the Big Island — prepare for the late Thursday landfall of Hurricane Eselle, they’re dealing with another natural hazard as well. A 4.5 earthquake struck on the island of Hawai’i around 6:24 a.m. local time, jolting already on-edge residents.

The quake, centered about 7 miles west-northwest of Waimea, was relatively shallow — only about 9.5 miles below the surface. At this point no damage is being reported and the Pacific Tsunami Warning Center tweeted that no tsunami warning would be issued.

Hawaii is no stranger to seismic activity, as the island state sits on top of a mid-tectonic plate plume of magma. Movement of subterranean magma is most often the cause of earthquakes in Hawaii, since it’s so far removed from fault lines. On average, Hawaii has about 50 earthquakes per year. Making the Aloha State the third most seismically active state, only behind Alaska and California.

Kiluea, which is also on the Big Island, is the most active volcano on Earth and has been erupting since January 3, 1983.
